SPECIFICATION forming part of Letters Patent No. 504,554, datedSeptember 5, 1893.

Application filed May 6,189 3.

To aZZ whom, it may concern.-

Be it known that I, GEORGE A. BURTNER, a citizen of the United States,residing at Altoona, in the county of Blair and State of Pennsylvania,haveinvented certain new and useful Improvements in Lamp-Burners; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to certain new and useful improvementsin lampburners of that class in which the upper part is hinged to allow of itsbeing thrown back when desired, and it has for its objects among othersto provide an improved burner which shall be simple, cheap andefficient, not liable to get out of order and which will avoid theobjectionable features of burners of prior forms. The lower portion ofthe burner is adapted to screw into the neck of the lamp in the usualway, the cap on which the screw is formed having openings in the sidedirectly opposite each other to allow a passage of air over the top ofthe oil in the lamp to carry off all the gas on the oil without itshaving to pass up through the flame of the lamp thus avoiding all dangerof explosion. The upper part of the burner is hinged to the cap so thatthe said upper part can be turned back to permit of easy filling of thelamp without removing the burner and avoiding the necessity ofunscrewing the burner from the neck of the lamp. lVhen the upper part isturned back it gives free access to the operating parts for cleaning orother purposes. The top of the upper part is air tight so that no placeis allowed for the flame to come in contact with the oil. Means areprovided for allowing a passage of air up under the cone to give a goodstrong draft, thus making a bright strong, light.

Other objects and advantages of the invention will hereinafter appearand the novel features thereof will be specifically defined by theappended claim.

The invention is clearly illustrated in the Serial No. 73,253. (Nomodel.)

accompanying drawings, which, with the letters of reference markedthereon, form a part of this specification, and in which- Figure 1 is aside elevation of a lamp burner constructed in accordance with myinvention. Fig. 2 is a view looking at the under side thereof with theupper portion thrown back on the hinge. Fig. 3 is acentral verticalsection through the same.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings by letter, A designates thelower portion which is in the shape of a collar having exterior threadsa to be threaded into the threaded neck of a lamp of any construction.At its upper edge this portion is provided upon diametrically oppositesides with the openings at, which allow for a passage of air over thetop of the oil in the lamp to carry oft or away all the gas on the oilwithout its having to pass up through the flame of the light, and thusavoiding all danger of explosions from the collection of gas in thelamp.

Bis the upper part of the burner to the under side of the horizontalportion of which is connected the hinged strip or wire I) which passesupon opposite sides of the partA and is secured thereto in any suitablemanner, the portion beyond the said part A being looped and formed intoa spring catch B, which is designed to engage over the edge of the saidhorizontal portion of the upper partwhen the burner is in its closedposition. By this construction all that is necessary when it is desiredto fill the lamp is to turn the upper part over to one side on itshinge, thus avoiding the necessity of unscrewing the burner from theneck of the lamp which operation soon 0 wears the threads and ruins theburner.

G is the cap upon the under side of the horizontal portion of the upperpart B; it contains the wick guide 0 and the wheels D by which the wickis raised and lowered in the 5 usual way by the stem or shaft E. Thiscap 0 is supported by the wick-guide and by the radial arms F which areextended to form the chimney-holding spring arms f; the top of this capis closed as shown, and upon each 100 side of the wick guide or tubethere is an opening g above the top of this cap to allow of a passage ofair up under the cone H to give a strong draft aiding in making a strongbright light. The cap 0 being open upon its under side gives free accessto the parts inclosed therein for repairs or otherwise. The cone H ishinged to the horizontal portion of the upper part as seen at h and uponthe 0pposite side it is provided With a spring catch I adapted to engagein an opening'in the said horizontal part.

A burn er constructed substantiallyas above described is simple in itsconstruction, there being no valve required; there is no opening fromthe flame of the light to the oil, thus making it impossible for the twoto come into contact, and thereby combining safety with good draft andease of filling and making in all a very convenient and safe lampburner.

hat I claim as new is The combination With the upper part and the lowerpart, of the Wire strip 1) hinged at one end to the upper part,embracing the lower part and secured thereto and formed opposite itsconnection with the upper part with a looped opening catch,substantiallyas shown and described.

In testimony whereof I afliX mysignature in presence of two Witnesses.

GEORGE A. BURTNER.
